Abstract:
We administered a calcium channel blocker, nicardipine 0.01 mg.kg-1 i. v. bolus or 5 micrograms.kg-1.min-1 i. v. infusion before induction with thiamylal or modified NLA (thiamylal, droperidol and butorphanol) to prevent hypertension at intratracheal intubation, and measured blood pressure and heart rate before and after intubation. Blood pressure of all experimental groups was significantly reduced in comparison with the control group right after intubated. Nicardipine is effective to prevent hypertension at intubation.
